Hello!
I am an Instagram marketing expert and have used Instagram to help my clients strengthen their relationships with customers and gain new customers. You're already doing well and have a plan in place which has worked for you, I will continue to follow that, however, I would do even more hashtag research and change up your content just a bit. For example, I would use a little bit of curated content, such as pictures of Miami and customer's pictures that they've posted under a hashtag. I have a lot of ideas running through my mind right now and would love to work on your project get back to me soon. Thanks.
Blake
